8. Describe the process of neural transmission.
The process of neural transmission begins with neurons, a nerve cell. This little cell has a body of a dendrite and an axon. Dendrites are little fibers that receive information and pass it on further into the neuron cell. The axon receives the message and sends it on to other neurons, muscles, or glands. Imagine them like telephone wires carrying information back and forth. Just like other electrical wires axons also need insulation to make sure the messages get transmitted intact. This insulation is called a myelin sheath and is made up of fatty tissue that speeds there impulses. An electrical charge can be from two to one hundred and eighty miles per hour.
When a neuron fires an axon opens its gates. These positively charges ions go through the cell membrane and causes another axon channel to open and then another like dominos. This process repeats up to a 100 or 1,000 times a second. There are two kinds of signals excitatory and inhibitory. Excitatory revs up a neuron while inhibitory is like slowing it down. Most of this communication takes place at a point known as a synapse. Neurotransmitters are little messages carried by chemicals that cross the synapse. These chemical molecules fit into a receptor and allow the other electrically charged atoms to flow in. The neurotransmitters ultimately decide whether to enable or inhibit a message from being received. Neurotransmitters influence hunger, thinking, depression, euphoria, addictions, and therapy. They help us learn and remember. They help us learn and respond. Neural transmission is important to virtually every system of the body.
Artifact #1
This is an illustration of a neuron. It is easy to to see how the dendrites are like roots gathering information to bring into the cell. It also gives a clearer picture of the myelin sheath acting as an insulator. Terminal buttons are what form junctions with other cells that allow the message to travel on.
Artifact #2
The image shows how each the process by which the neural transmission process happens.
